Manual transmission/transaxle review

What is the purpose and function of a transmission?

• Allows the vehicle to accelerate up a hill

• Allows the engine to accelerate the vehicle

• Allows engine speed to be reduced at higher speeds to save fuel

• All of the above

Which part is splined to the clutch disc?

• Main shaft

• Countershaft (lay shaft)

• Main gear

• Cluster shaft

In a manual transmission, engine torque is applied to the ________ when the engine is running and the clutch is engaged.

• Cluster gear

• Input shaft

• Main gear

• All of the above

The free rotating gears on the main shaft of a RWD manual transmission are called ________ gears.

• Hypoid

• Speed

• Fixed

• Floating

Which part of a synchronizer is splined to a shaft?

• Synchronizer sleeve

• Hub

• Speed gear

• Synchronizer blocker ring

A rear-wheel drive 5-speed manual transmission is being discussed. What is the gear ratio when the transmission is in 4th gear?

• 1:1

• 8:1

• 1.5:1

• 3:1

A customer complained of hard shifting, particularly into first gear and reverse. Technician A says that the blocking ring maybe worn. Technician B says that the clutch may be defective or out of adjustment. Which technician is correct?

• Technician A only

• Technician B only

• Both technicians

• Neither technician

A manual transmission is difficult to shift but only when the outside temperature is below freezing (32 F or 0 C). Technician A says that the brass blocking ring could be defective. Technician B says that incorrect gear lubricant could be the cause. Which technician is correct?

• Technician A only

• Technician B only

• Both technicians

• Neither technician

Technician A says that the torque available at the output shaft is greater in second gear than when the transmission/transaxle is in third gear at the same engine speed. Technician B says that the output shaft is rotating faster when the transmission/transaxle is in second gear compared to third gear when the engine is at the same speed. Which technician is correct?

• Technician A only

• Technician B only

• Both technician

• Neither technician

Two technicians are discussing how torque is increased inside a manual transmission/transaxle. Technician A says that the gear ratio in first gear between the main shaft and the countershaft should be multiplied by the ratio of the corresponding countershaft gear and output shaft gear. Technician B says that the two ratios should be added together. Which technician is correct?

• Technician A only

• Technician B only

• Both technicians

• Neither technician
